Anophthalmos with limb anomalies

M icrophthalmia,anophthalmia, andcoloboma comprise the MAC spectrum of ocular malformations. Microphthalmia refers to a globe with a total axial length that is at least two standard deviations below the mean for age. Anophthalmia refers to complete absence of the globe in the presence of ocular adnexa (eyelids, conjunctiva, and lacrimal apparatus). Coloboma refers to the ocular malformations that result from failure of closure of the optic fissure. Chorioretinal coloboma refers to coloboma of the retina and choroid. Iris coloboma causes the iris to appear keyhole-shaped. Microphthalmia, anophthalmia, and coloboma may be unilateral or bilateral; when bilateral they may occur in any combination. [from GeneReviews]

Tourette Syndrome

Tourette syndrome is a neurobehavioral disorder manifest particularly by motor and vocal tics and associated with behavioral abnormalities. Tics are sudden, brief, intermittent, involuntary or semi-voluntary movements (motor tics) or sounds (phonic or vocal tics). They typically consist of simple, coordinated, repetitive movements, gestures, or utterances that mimic fragments of normal behavior. Motor tics may range from simple blinking, nose twitching, and head jerking to more complex throwing, hitting, or making rude gestures. Phonic tics include sniffling, throat clearing, blowing, coughing, echolalia, or coprolalia. Males are affected about 3 times more often than females, and onset usually occurs between 3 and 8 years of age. By age 18 years, more than half of affected individuals are free of tics, but they may persist into adulthood (review by Jankovic, 2001). [from OMIM]
